MidOpt LP Series – LP286 Protective Window

Salient Features

LP286 Borofloat® Oleophobic VIS A/R Coated Protective Window

LP286 windows are made with high-impact, thermal-resistant Borofloat®, which is transparent in the near-UV, visible, and near-infrared ranges. It has a very low coefficient of thermal expansion and high shock resistance, withstanding temperatures up to 450° C for extended periods of time. Borofloat® is resistant to staining and harsh chemicals such as acids or alkalis, making it the protective window of choice when an economical window is needed for use in a harsh, high temperature environment. MidOpt LP286 windows have a rugged multi-layer, broadband anti-reflection coating to limit reflection loss in the visible and near-infrared spectrums. These windows are also available with an oleophobic (anti-smudge) coating to resist oils and moisture build-up, allowing for much easier cleaning.

MidOpt StablEDGE™ optical filters are specifically designed to be less  susceptible to effects from angular shifting seen when optical filters are placed in front of short focal length (<12 mm) camera lenses.
StablEDGE™ filters take advantage of absorptive filter glass to form the leading
edge of the filter passband.This assures no shifting in this region, even when the
lens FOV exceeds 100°.StablEDGE™ designs are  less angle-of-incidence sensitive, inherently more rugged, and are environmentally stable.

 

MOUNT & SIZE OPTIONS: In-stock, ready-to-ship Protective Filters are available in Threaded Mounts, sizes M13.25 to M105; 25.4® C-Mount; Slip Mounts; or Unmounted. Custom shapes and sizes are available.
